ANTIRATTLING DEVICE FDR FIFTH-WHEELS.

SPECIFICATION forming part of Letters Patent No. 598,397, dated February 1, 1898.

Application filed February 16, 1897. Serial No. 623,720. (No model.) I

To all whom it may concern.-

Be it known that I, HENRY C. SWAN, of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented a new and useful Improvement in 'Antirattling Devices for Fifth-Wheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows in bottom plan view a fifthwheel for vehicles constructed in accordance with my invention. Fig. 2 is a vertical section on the line II II of Fig. 1, and Fig. 3 is a vertical section on the line III III of Fig. 1. Figs. 4, 5, and 6, on the second sheet of the drawings, are like views illustrating a modified construction, Fig.4 showing a bottom plan view of the fifth-wheel. Fig. 5 is a verticalsection on the line V V, and Fig. 6 is a vertical section on the line VI VI of Fig. 4.

The object of my invention is to provide fifth-wheels with an antirattling device of improved construction which shall have special advantages of strength, simplicity, and efliciency.

The nature and scope of the invention are sufficiently indicated in theclaims.

Referring to the figures on the first sheet of the drawings, 2 is the upper circle-plate, and 3 is the lower circle-plate, of a fifth-wheel, and 4 4 are the perch-irons. The antirattling attachinent consists of a bowed spring 4, the middle part of which is supported by and fixed to a chair 5, extending between the perchirons, and the free ends of which bear against the under surface of the lower circle-plate.

To fix the spring to the chair, I employ a rivet 6, and to make a sliding connection between the ends of the, spring and the lower circle plate I form on the under surface of the latter a groove 7, and on the end portions of the the groove and serve to maintain the parts in proper relative position. The ends of the spring bear against the circle-plate with sufficient pressure to prevent the same from rattling, and a simple and very effective device is thus provided.

Various modes of supporting the spring may be employed within the scope of my invention as broadly construed. Thus in Figs. 4:, 5, and 6 I show a supporting chair or bracket 5 extending from a lug 9 on the upper circle-plate, to which it is attached by a bolt 10. This chair or bracket extends back under the lower circle-plate and the spring is riveted to it at the middle, as above explained.

I claim- 1. A fifth-wheel having a groove on the surface of the circle-plate, and a spring having a projection which fits within the groove.

2. A fifth-wheel having a bowed spring, whose middle portion rests on a chair or support, and whose free ends fit Within a groove on the lower circle-plate.

3. A fifth-wheel having in combination with double perch-irons, a bridge or support extending between the same, and a bowed leafspring whose middle portion is fixed to said bridge or support and whose ends extend upwardly therefrom and engage the lower circle-plate.

In testimony whereof I have hereunto set my hand.
